実用化に向け行き詰まりを見せていたマルチホップ無線センサネットワークが,同時送信フラッディング(CTF)のもたらした強烈なインパクトにより,全く新たな技術に生まれ変わろうとしている.筆者らは,CTFが提案された当初からその重要性を認識し,全ての通信をCTFで行うセンシング基盤Chocoの開発を進めてきた.また,実フィールドにおけるCTFの有用性を明らかにするため,社会的要請の強い橋梁モニタリングシステムをChocoを利用して開発し,実橋梁において10台〜70台といった規模で実証をも進めてきた.本論文では,CTFが無線センサネットワークにもたらした変化について論じるとともに,CTF利用型センシング基盤Choco,及びChocoを用いた構造モニタリングシステムの開発について述べる.また,実証実験から得られた「シンクノードも含めノードの移動に頑健なため設置が簡易である」「中継ノードを増やせば繋がるため無線に対する深い知識がなくても構築できる」といったCTFの運用時における特性についても示す.

Our previous research disclosed that oral reading such as "read and look up" combined with "personalized oral reading" is highly correlated with speaking ability. This is because this sort of oral reading embeds semantic and grammatical verification and restructuring, and thus increases learners' cognitive load. This result led to a further hypothesis; if oral reading instruction which involves high cognitive load is continued for a certain period of time, learners' speaking ability can be improved. A two-month experiment was conducted to verify this hypothesis with the first-year upper secondary school pupils as the participants. The participants were divided into two groups according to the different degrees of cognitive load accompanying the oral reading activities they were engaged in. The result of the experiment disclosed different levels of improvement in the participants' speaking ability, depending upon different degrees of cognitive load of the oral reading activities; greater cognitive load led to greater improvement in speaking ability. This finding endorses the pedagogical value of oral reading activities as preparatory practice in speaking as long as they involve high cognitive load.

若年性糖尿病患者の糖負荷試験で,調節麻痺眼にも近視化と眼圧降下が生じる。こうした屈折調節系の変化が高血糖に基づくものか否かを明らかにする目的で,調節麻痺剤点眼処置をした若年健常人5名に経口糖負荷を行い,血液生化学と屈折調節系の変化を調べた。糖負荷により,血糖値と血漿浸透圧が上昇し,眼圧の降下,屈折度の近視化,浅前房化,水晶体の肥厚が生じた。近視化の程度は,調節麻痺による残余調節力以上の変化を示した。負荷後の血糖値正常化に伴い,眼圧は正常化し,近視化も改善した。以上の結果から,高血糖に伴う近視化は,眼圧降下によって生じたチン小帯張力の減少が誘発した水晶体肥厚に基づくと推論された。遠視化は血糖正常化に伴う近視化の改善によると考えられた。

34歳男性が前日からの急激な近視化を主訴として受診した。裸眼視力は従来は左右とも1.5であったという。初診時には右眼に-3.5D,左眼に-3.0Dの近視があった。軽度の毛様充血と浅前房があったが,明らかな虹彩炎の所見はなかった。蛍光眼底造影で斑状の色素漏出,髄液に細胞増多があり,原田病と診断した。メチルプレドニゾロンによるパルス療法とプレドニゾロンの内服で多発性滲出性網膜剝離は軽快し,右眼+1.0D,左眼+0.5Dの遠視になった。この症例は,原田病が急性近視で初発する可能性があることを示している。

血糖低下時に視力低下を認めることがあるが, その頻度・血糖値との関係についての報告は少ない.血糖低下に伴い一過性の遠視化 (最大屈折変化 (以下△Dと略す) は+2.25) による視力低下を認めその改善に数ヵ月を要した1例を経験し, 以後の例でコントロール前後での屈折状態を検討し, △Dと血糖低下幅 (以下△PGと略す)・血糖低下速度との関係を検討した.10例中9例で屈折異常 (全て遠視化で△Dは+0.25-+2.75) を認め, △Dと△PG間では両眼 (右眼: n=10, r=0.888, 左眼: n=10, r=0.863, 共にp<0.01), △Dと血糖低下速度間では右眼 (右眼: n=10, r=0.722, p<0.05, 左眼: n=10, r=0.613, ns) で有意の相関関係を認めた.血糖改善時には多くの例で屈折異常を認め, うち約3割に視力低下を認めた.△PGが100mg/dl以上で屈折異常を生じ, それが大きい程症状として自覚されると考えられた.また, 血糖改善時には網膜症以外に屈折異常を考える必要性が示唆された.

This report describes a survey of mole's tunnel in river bank. The situation of mole's tunnel in river bank has been hardly known until now. This survey is that the plaster water was put into the mole's tunnel in the old bank of the Chikugo river and after the plaster fixed, the bank was cut and opened.After that the depth of the tunnel and its extent were recorded. The data is valuable to study the influence of mole's tunnels in the aspect of leakage, piping and slope collapse of the river bank.

Since the previous paper was published elsewhere (vol.9, No.1, of this Journal) the writer has been able to extend the range of his work both as to number of persons tested and variety of locality, by which means he was enabled to obtain the reactions of about 7500 new subjects. The present paper is a report of a part of the results derived from the combined materials, new and old.Using the chemical compound, para-ethoxy-phenyl-thio-carbamide, 8824 Japanese, 5933 Formosans (Chinese origin), 1756 natives (Formosan aborigines of various tribes) were tested and their reactions reported in writing or orally. In all races the reaction showed great individual divergences, some experiencing a bitter taste, others finding the compound sweet, sour, or salty, while by some no reaction was felt apart from tactual sensation. Roughly classified, the reactions may be said to fall into three categories-the tasteless, the bitter, and the others. The frequency proportion of the bitter reaction was the highest, the tasteless the next, and that of the others the lowest. This order was alike for all races.(cf: Tables I and II.)The actual size of the frequency percentage for the same category, however, showed the existence of a great difference between the various races. The frequency percentage of the tasteless was found to be largest for the Japanese people, the figures for the Formosans were as small as about 50% of those for the Japanese, while those for the natives were less than one eighth of those for the first. Of the three native tribes, the Atyal has the largest ratio of non-tasters, though compared with that of other races it is very low; in the case of the other two native tribes it is almost negligible. The percentages of the bitter-tasters were found to be just the inverse of those for the non-tasters, in the same order of race, as given above, i. e. lowest for the Japanese and highest for the natives. As a matter of fact, the existence of the racial difference in respect of the frequency of non-tasters of the compoud-so also that of the bitter-tasters-is doubtlessly conclusive, and would appear to deserve more extensive and analytical investigation, for such a remarkable difference promises to lead to the discovery of some essential racial characteristic of service in the study of many important aspects of scientific and practical data when more carefully elaborated. The racial difference in the frequency of the sweet and other tasters, on the other hand, presented itself as insignificant when having regard for probable errors.(cf. Tables II, III, IV.)In connection with these racial differences, some of the conditions which might be suspected as affecting the difference, and might often complicate or even lead to wrong conclusions in extreme cases, have been studied in so far as the statistical method is concerned. First: Comparing the percentages of the tasteless cases for the populations in the north, middle and the south of Formosa (average temperature: 21.6°, 22.1°, 23.1°C. respectively), no statistically significant difference was found, which suggests that no local influence affects the ratio.(cf. Table v.) Of course, since the local conditions possibly responsible for the ratio may be numerous and vary greatly, a decisive conclusion as to local influence in general has yet to be worked out. But it is demonstrated, in the present study at least, that no local influence capable of affecting the racial difference can be isolated. Second: Statistically significant differences in percentage among the tasteless was not found between the sexes of all the Japanese, Formosan and Atyal peoples.(cf. Table VI.) Moreover with the Japanese the sex difference in this category was statistically examined at age intervals of two years and the percentages of the non-tasters of the one sex was compared with that of the other in the corresponding age class.
